Specification of Letters Patent.

Patented sept. 3, 1918.

Application filed January 18, 1918. Serial No. 212,408.

To all 'whom t may concern.'

Be it known that I, CEcIL M. CLARKE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Sheathing Materials, of which the following is a specification.

My invention relates, more particularly, to sheathing material for covering the sides and roofs of buildings and which is formed of a foundation of Waterproofed felt or any other suitable, preferably flexible, material and which preferably, though not necessarily, is provided with a wear-resisting coating of any desirable form and which is exposed to the elements in the use of the sheathing, this coating being preferably formed of any suitable particles attached to the foundation as is common in prepared roofing.

More particularly stated, my invention relates to prepared sheathing material provided in strips,l each of which presents a body' portion from which a plurality of shingle-forming sections, arranged in a series, project, these shingle-strips being so constructed that when-assembled together in overlapping relation on a structure to be sheathed, the appearance will be the same as that presented by a structure covered with shingles, as commonly laid. The present invention constitutes an improvement over the invention forming the subject of my pending application for United States patent on sheathing material, Serial No. 209,008, filed Dec. 26, 1916, which lis directed to the provision of shingle-strips of such construction that they will not present the disadvantage in use of becoming curled or upwardly deflected at. their unsecured corner-portions, by reason of the action of the sun, rain, and Wind. My present invention provides for the accomplishment of the purpose just stated, and in addition, enhances the shingle effect.

Referring to theaccompanying drawing:

Figure 1 is a plan View of a shingle-strip constructed in accordance with my invention; and Fig. 2, a` plan view of a section of roofing formed of a plurality of the shingle-strips shown in Fig. 1.

My invention consists in providing a strip of any desirable sheathing material, as, for example, such as that above referred to, and commonly employed for roofing purposes, of any desired length and Width, with slots 3 provided therein, preferably in parallel relation and arranged crosswise of the strip at equal distances apart. These slots extend relatively close to one edge of the strip which, in the construction illustrated, is the lower edge as represented, preferably to within about two inches of such edge, and preferably a relatively great distance from the opposite, upward, edge of the strip as shown. Notches represented at 4 are provided in the lower edge of the strip, these notches, which are relatively shallow and in a strip of the size commonly provided may, for example, be approximately one inch deep, alining with the slots 3. The slots 3 are thus connected across their opposite ends by portions ofthe sheathing strip as shown, and by the construction described, the lower edge of the sheathing strip presents a series of shingle-sections 5, which are connected together at their lower ends by the uncut portions, or webs, 6 of the strip.

Each strip, which may be of such length as to provide any desired number of shinglesections 5, is preferably of such width that in the assembling of the strips on a structure to be sheathed, as shown in the drawing, and in accordance with-the common practice of laying shingle-strips, the solid portions 7 of the shingle-strips will be overlaid by portions of two superposed shinglestrips and each shingle-strip will expose to view shingle-sections 5 of sufficient dimensions to present the desired shingle appear- -ance to the structure covered by the strips.

The slots 3, by preference, are of such dimensions and are so disposed relative to the opposite edges of the strip as shown, that -the desired overlap referred to and shingle appearance are presented While maintaining the body portion '7 of the strip in substantially unslotted condition, this being done by so disposing the slots 3 that when the strips are assembled, the upper end walls of the slots Will be covered by the lower edges of the overlying shingle sections 5.

In producing my improved shingle-strip, I may\ provide the foundation material,

'treated as desired, and coated, if desired,

to form a weatherproof wear-resisting material all in accordance with com-mon practice, and then, by any suitable device or mechanism, cut the material into shinglestrips of any desired length, though it will be understood that my invention is not limited to the use of any-:particular material,

nor to the production of the article by any particular method of manufacture.

A shingle-strip constructed in accordance with my invention presents in the finished article ready to be applied to a structure to be sheathed, a series of shingle-sections', the lower ends of which are restrained against curling or outward deflection under subjection of the elements, by the webs 6, and thus the shingle-sections 5 will lie flat against the portions which they superpose; and the provision of the relatively shallow notches 4 serves to enhance the shingle effeet, without subjecting the shingle-sections to objectionable curling or outward deflection.

The shingle-strips are preferably laid in theoverlapping relation, and with the shingle-sections of adjacent strips disposed 1n staggered relation, as shown in Fig. 2, and which is the common practice in the laying of shingle-strips to produce the same appearancel as that presented by a structure sheathed with shingles.

Vhile I have illustrated and described a particular construction in which my invention is embodied, I do not wish to be understood as intending to limit it thereto, as the saine may be variously modified and altered without departing from the spirit of my invention.

What I claim as new and desire to secure by Letters Patent is- 1. As an article of manufacture, sheathing material formed of a strip of waterproof material containing a series of slots which extend at their ends short of opposite edges of said strip and form shingle-sections along one edge thereof, said 'slots extending relatively close to said last-referred to edge, whereby said slots are connected across their opposite ends by web-portions of said strip, one of the edges of said strip containing a series `of relatively shallow notches, all of the portions of said strip being of substantially the same thickness and extending in the same plane adapting a plurality of strips of the sheathing material to be laid in flatwise relation Without fastening devices engaging the exposed portions of said strips.

2. As an article of manufacture, sheathing material formed of a strip of waterproof material containing a series of slots which extend at their ends short of opposite edges of said strip and form shingle sections along one edge thereof, said slots exflatwise relation without fastening devices j engaging the exposed portions of said strips.

3. As an article of manufacture sheathing material formed of a stripof waterproof material containing a series of slots which extend at their ends short of opposite edges of said strip and form shingle sections along one edge thereof, said slots extending relatively close to said last-referred to edge and the upper edges of said slots being closer to the lower edge of said strip than to the upper edge thereof, whereby said slots are connected across their opposite ends by web portions of said strip, one of the edges of said strip containing a series of relatively shallow notches, all of the portions of said strip being of substantially the same thickness andu extending in the same plane adapting a plurality of strips of the sheathing material to be laid in flatwise relation without fastening devices engaging the exposed portions of said strips.

4. The combination with a structure to be sheathed, of sheathing material on said structure in the forni of a plurality of strips arranged in overlapping relation and each v formed of waterproof material containing a series of slots which extend at their ends short of opposite edges of said strip and form shingle sections along one edge thereof. said slots extending relatively close to said last-referred to edge, whereby the slots of each strip are connected across their opposite ends by web-portions of the strip, one of the edges of said strips containing a series of relatively shallow notches, all of the portions of each strip being of substantially the same thickness and extending in the same plane adapting the strips to be laid in Hatwise relation, said strips being arranged with their shingle-sections in breakjoint relation and with their exposed portions free of fastening devices.
